LINOTYPE-MACHINE.

Application filed November 30, 1912, Seria1 No. 734,325. Renewed August17, 1915. Serial No. 46,016.

To all whom it may concern.-

Beit known that I,W]11,IAM E. BERTRA'M, a citizen of the United States,residing at Brooklyn, in the county of Kings and State of New York, haveinvented new and useful operator by'means of the keyboard and assembledin a line on either or both of two difierent levels, and the line thusassembled is delivered to an elevator known as the first elevator whichcarries the line to a casting vented, fails to lock the transfermechanism, 1

in which event its operation is very destructive of the matrices whichare'on different levels.

The objectof this invention is to provide anautomatic latch operated bythe action of the first elevator which will lock the transfer slides andprevent the discharge of the line in case the operator failed tomanipulate and lockit by hand, thereby insuring certainty in theoperation of themachine. V v 0 To these and other ends, the lnventlonconsists in certain improvements, and com binations and-arrangements ofparts,- all.as

will be hereinafter more fully described, thenovel features of theinvention being pointed out particularly in the claims at the end of n,the specification.

In the accompanying drawings:Figure 1 is a front elevation of a portionof a lino type machine showing the first elevator and the related partswith the present invention, applied thereto; Fig. 2 shows, on anenlarged scale, the matrix transfer channel and slide, an automaticlatch embodying the present invention being shown in full lines incooperative relation with the transfer Patented Jan.

slide, and the broken lines indicating the up- I permost position of thefirst elevator and the disengaged position of the latch; Fig; 3 is aperspective view showing in detail the matrix transfer "slide and thecooperative latch; Fig. 4 is a side elevation showing the first elevatorin section and illustrating thestop for limiting the upward movement ofthe first elevator; Fig. 5 is a viewof the lower portion of Fig.- 4 asit. appears from the right, showingv the limiting stop for the firstelevator. w

Similar parts are designated by the same reference characters in theseveral views.

The invention in the present instance'is shown in connection with alinotyp'e machine of the usual and well known construetion, 1designating the 'first elevator carry.-

ing the usual jaws 2, and 3 designating the.

from the" channel 4 forming a part ofthe. matrix-assembling mechanism"while in an intermediate position, and whenthe first elevator movesdownwardly into its lower posltion, it conveys the assembled'line 'ofmatr ces to a'position between the jaws of the vise 3 which operates inthe usual way to clamp the line before the mold on the mold wheel 5.

In the usual operation of linotype imachines,the first elevator risesand lifts the line of matrices, after a cast has been made therefrom, upto a position where the line levels, a movable rail 8 serving to supportthe matrices at the upper level, and this rail may be retracted by anysuitable-or well known means at the moment the first elevator reachessubstantiall the limit of its upward movement, where y all of the matofmatrices 1s transferred to the distributing latch is provided with atrip 13 which is inrices in the line will be positioned at the samelevel immediately before the slide 7 operates to transfer the line of.matrices from the first elevator tothe distributing mechanism. 1

According to the present invention, the transfer slide 7 is providedwith a notch 9, and a latch 10 is provided, this latch being pivoted atll'to a suitable stationary part of the machine and is provided with adog or projection 12 which is adapted-to engage in the notch 9 of thetransfer slide while the latter is in its retracted position and therebyprevent operation of the slide to transfer theline of matrices from thefirst elevator to the distributing mechanism. This the line of movementof the rear jaw of the first elevator. This latch which may operate bygravity automatically engages With and locks .thetransfer slide at eachtime the slide-reaches its retracted position, and when the machine isoperated in the usualmannor to distribute the matrices after each casttherefrom, the first elevator upon reaching the'limit of its upwardmovement will abut I from. the first elevator to the distributingagainst the trip, 13 of the latch 10, thus transferring movement fromthe elevator to the latch and causing the dog 12 of the latch todisengage from the notch '9 of the slide, thereby unlocking the slideand. permitting the latter to o crate and perform its function of transerring the line of matrices mechanism. The final upward movement of thefirst elevator also serves to' retract the rail 8 and thereby permitsuch matrices as I were assembled at the upper level .to drop to thesame level with the-dower matrices. However, when it is desirable torepeat the casting operation using the same line of matrices, the upwardmovement of the first elevator is limited or arrested so as to avoidretraction of the rail 8, thereby maintaining the matrices in theline inproperly assembled condition and preventing tripping of the latch 10,whereby the transfer slide 7 .will remain locked. A limiting stop 14 isprovided in the present instance which is pivoted to asuitable portionof the stationary frame at 15, and an abutment, pref-- erably in theform of a set-screw 16, is provided on the first elevator which, ,whenthe stop 14 is set in one position, will come against the stop andthereby limit the upward movement of the first elevator, preventingrestoring of the matrices to a 'common level, and maintaining thetransfer slide 7 in locked condition, such relation of the parts beingshown in Fig. 4. The thickness of the stop ,14 corresponds to the distance at which the first elevator will be arrested below its uppermostposition. When it is desirable to resume the usual operation of themachine, that is to say, to cause each line of matrices to. bedistributed after a single cast has been made therefrom, it isonlynecessary to move the stop 14 into a position where it will clearthe abutment 16 on the first elevator, the latter then being permittedto reach its uppermost position -where the rail 8 will be retracted andthe bar 17 will operate to bring all'the matrices in the line to acommon level, and the latch 10 will be tripped to permit theusualoperation of the slide 7 to transfer the line of matrices tothedistributing mechanism.

I claim as my invention 1.- In a-linotype machine, the combination of amatrix-carrying elevator, a trans latch cooperative automatically withthe 'slide'tolock the same in retracted position and releasable by theelevator when the-lat: ter reaches substantially its uppermost position,and a limitingstop adapted when in its nation of a matrix carrier totransport the matrices from one position to another in the machine aftercasting for distribution, a

in proper operative relation to each other.

4. In a typographical machine, the combinationof the elevator to presentthe matrices for casting and movable vertically to deliver them fordistribution, means for transfer ring the matrices from the elevatorwhen in its uppermost position, and locking means controlled by theelevator to prevent the operation of said transfer means when theelevator fails to rise to the proper extent.
